TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,500, dated May 6,1890.

Application filed November 28, 1888. Renewed March 28, 1890. Serial No.345,632. (No model.)

To all whom it may concern.

Be it known that I, ARTHUR WISE CASH, of Bridgeport, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Type-Tritin g Machines, of which the following is afull, clear, and exact description, whereby any one skilled in the artcan make and use the same.

My within-described improvement relates more particularly to atype-writing machine of the general construction shown and described inmy patent of November 1, 1887, No. 372,602, in which a reciprocatingribbonguide is employed to move the ribbon sidewise to cover and uncoverthe point upon which the type is caused to strike; and the object of myimprovement is to provide a movable ribbon-guide that will move theribbon sidewise with greater ease and accuracy and by simpler means thanis shown in the patent above referred to.

My invention consists in the combination, with the frame of the machine,of a key-lever, the rock-bar, a rod connecting the said rockbar with aswinging guide that is pivotally supported at one end on the frame andextends along the front of the machine in the direction in which theribbon runs, and that bears on its outer end a ribbon-guide; and itfurther consists in details of the several parts of the apparatus andtheir combination, as more particularly hereinafter described, andpointed out in the claims.

Referring to the drawings, Figure 1 is a plan View of so much of atype-writing machine as is necessary to illustrate the location andmethod of operation of my improvement. Fig. 2 is a detail view, in rearelevation, of a part of a type-writing machine, showing my improvedattachment and the directlyrelated parts. Fig. 3 is a detail viewshowing the rock-shaft, ribbon-guide, and connected parts.

In the accompanying drawings, the letter 7) denotes the top plate of thebase or frame of the machine; I), the type-base borne on the top plateI), that also supports the key-levers c, with the usual key a and thespace-bar. A bearer 6 extends across the inner ends of all f extendsdownward from this rock-bar f through an opening in the top plate of themachine, and is connected by a rod 9 to the side of the ribbon-guide 11.This ribbonguide I-I consists, preferably, of an arm h, extendinglengthwise of the ribbon, and avertical arm h, that is pivotallyconnected to the upright post a, that extends between the top and thebase of the frame of the typograph. This arm is held against verticalmovement; but is pivoted to rock on the post.

On the outer end of the arm h is formed a ribbon-guide 77, that consistsof loops or slots upon opposite sides of an opening. The ribboni extendsfrom the ribbon-reel downward along and overlying the guide-arm, and isthreaded through the guide-loops. The outer edge of the guide bears anindex F1 that indicates the exact position upon which the type willstrike. The ribbon is wound from one reel to another across the machinein any usual and well-known manner.

By means of the device above described, when a key-lever is depressedthe rock-baris moved so as to throw the arm f toward the key-base, andthis moves the ribbon-guide connected to the arm by the rod, as alreadydescribed, outward, and bears with it the ribbon into a position so thatthe type-bar that is operated by the depression of a key-lever.

strikes its type-face directly upon the inkingribbon, and as soon as thepressure upon the key-lever is removed the latter is lifted, therock-bar swung back, and the ribbon-guide swung back with it, uncoveringthe spot upon which the imprint has been made.

I claim as my invention- 1. In a type-writing machine, in combinationwith the frame, the key-lever pivoted to the frame, a rock-shaft inoperative connection with the key-lever, the crank-arm fast to therock-shaft and connected to the ribbon guide, and the ribbon-guidepivotally supported on the frame of the machine, with an arm extendinglengthwise of the ribbon and terminating in a guide through which theribbon is threaded, all substantially as described.

2. In a type-writing machine, in combination with the frame, thekey-lever pivoted to the frame, the bearer overlying the key-lever andconnected to a i'oclesliaft, a rock-shaft with the crank-arm andconnecting-rod that 10 unites the rook-bar and the ribbon-guide, and Ithe ribbon-guide pivotally supported on the frame of the machine, withan arm extending, lengthwise of the ribbon and terminating in a guidethrough which the ribbon is threaded, all substantially as described. 4
